my computer power cycles when i switch it on ,then i later went in for assus hd 6970 direct cu and when i am gaming it shuts down and restarts.i am using a quiet psu 550 watts which have 12 rail volts @ 18 amps .what could be causing this
 
Solution
Most like your power supply is too small for the job. The Asus draws 190w when engaged which is 15amps. Move up to a PSU with more amps on the rail.
